Hello,
I'm trying to get upnpc to work but actually it doesn't...
I think that 2 stuff can cause the problem:
- having no minisspd running (dunno if miniupnpc does send sspd packets without it)
- interfaces are changed some time ago (I suppose this is the problem)
I wrote it here as I annoyed kinda all the Arch community with it ;P
Also, how is the -m flag meant to be used?
Because I tried
Code:
upnpc -s -m wlp3s0

But it does not work D:

After disabling the firewall it does work...
Had to check the interface a few times! Razz
What port does upnpc use? And... is there a way to load default interface from ifconfig?

SSDP (UPnP discovery) uses UDP on port 1900.
what do you mean by "is there a way to load default interface from ifconfig" ?
If you don't use -m option, default interface will be used.

I'm glad to inform you that I'm a derp. Razz
I had to enable any kind of traffic in UFW for my LAN in order to have it working fine... and now it works Smile
To be exact, I had to:
Code:
ufw allow from 192.168.0.0/24

Problem solved Wink

A more exact rule would be to allow any incoming traffic on port 1900 with a protocol of UDP originating from my network:
Code:
sudo ufw allow from 192.168.0.0/24 port 1900 proto udp to any


If there were exploits in your router or something, you may save yourself from revealing all of your network information.
